To @il whom it may coi/wem:

Be it known that l, Wnnmm "Wfolecrn a. citizen of the United States, residing; et

' Philadelphia, county of Pixiladelpliiegfand @tete of Pennsylvanie, beve invented s-new and usefullV improvement in Automobile- Brekes, of which the followingis e-tull, clear, end exact description, reference being iisd to the accomponyin drawings, which' form a part of this speci cati-on.

The' object or" my invention is to eiiectively apply e braking action to an automobile wheel or to any other Wheeled vehicle' lby bringing e disk rotating with the Wheel 'into frictional contact with one` or more ynon-roteting plates and preferably 'yvitli one or both of two peirs'of concentric annuler plates connected respectively to the devices adapted for independent actuation. byfthe hand end by the foot.

`A preferred embodiment of the invention `is shown in the accompanying drawings, in

Figure 1 is a fece view of the apparatus showing more'especieliythc devices for 0peretingboth scts'of bre-ke-piates. Fig. 2 is a, section on the ine 22 of Fig. l. Fig. 3 is e section looking in the direction of the arrow 3?) of Fig. 2. Fig. 4 is a section 0n 'the line 4.-# 1 of Fig, ul, showing; the liendectneted device for rictionelly applying the inner pair'of friction plas. Fig. 5 is f e vieri looking in the direction of the arrow ets ci' carri/ing on annuler disk e.

5.-5 of Fig.' 1, showing the foot operated device for frictionnlly applying the outer pair ot friction plates. Fig. 6 is n perspective Tview of two of the slides (connected to one pair of friction plates) which are operated by one of the actuating devices above named. Fig. 7 is o perspective view one et vthe vwedge sections ci one of tire actuating devices.

iiitliin tbe axle tube a is the axle b to 'which is secured the wheel, one edge of tlier *parallel to the axle. @ne set of tubes ne receives sliding'members which connect with friction plates f, The other set of tubes n receives sliding members connected with friction plates g., g. Thus, to the friction `plete f nearest thelixed plate is secnured e bracket c" supporting n semi-circuler slide c' extending into the tube m. To the :triction plete f on' the other side oidisls c is secured n bracket' j carrying s' slide j extending into the tube alongside. slide c" and being, tlirougliout this part of its length, o? semi circular cr slide e' and li'cving an end or heed of circuier cross-section which is spaced from. slide 11 to receive e wedge hereinafter described.

The end of tube m is closed bye threaded ossl-sectiombnt extending beyond plug" o. A spring 79, confined between plug ,i

' o and heed of slide j, tends to maintain the more distant plete f spaced from disk e. The other set of tubes ce receives similar siides 7c und Z which uresimultonecuslveonnected to the two plates g, g. These'tilbes have also threaded plugs o and springs p.

There is e wedge 1' Jfior cach tube m and n Wedge /v for each tube n.v The set of wedges r is carried on the inside oi c turnnble ringe to which 'is secured an erm i which, through suitable connections, may be operated man nelly (pregternblv by hand)l tri-turn ring s so as to cause each wedge 9 to pass between the end of Le slide 'i and the head o'colre4 sponding slide ,ftherebv causing the slis to more in opposite directions and applying' both plates f, f vto the dislre.

`The set of wedgesffv 1s carried on the out side or" n turnnble ring' w to which-is secured nn crm o which, through suitable connections, muv be operated manually (preferabljv by foot) to turn ring w so as to cause cach wedge 'u to poss between the end ot o slide I: and the bend of corresponding slide l, tlierebv causingr the slides to move in opposite directions und applying' both plates g, f/ to tbe disk e. Leni? springs 1/ muy be arranged between tbe plates f, on one side of disk e :ind the plates f, y. on the other side oi dislc c thereby holding nil the plates out ot' Contact with the disk.l

The described construction. which muy be Y modified in detail without departing from my invention, is not expensive to construct, occupies n small ninount of space. nliords n ,errent uren of' brake surface, sind operates with, euse. smoothness. certainty :md power@ Having now fully described my invention,

- 1. A disk brall. comprising a friction disk wheel,a. pair of annular friction plates, said plates arranged on opposite sides of the numberof pockets carried thereby, slides secured to the nearer friction plate and extending into said pockets,slides secured to the more .distant friction plate and extending into saidv pockets and beyond the otherl v`slides, wedges each extending between a ."pair of slides in one ofthe pockets, and a- 1 manually operable turnable device carrying said wedges.

i". A disk' brake comprising a friction disk "l turning with Vthe wheel, a pair of annular friction. plates,

A disk brake comprising a friction disk wheel, two pairs of anaXis, the two plates `j ofeach pair located on opposite sides of the fao'` ftwo plates of each pair toward each other against opposite faces disk, and means to simultaneously move the of the disk( SHA disk plate comprising -a wheel, a brackets secured to the wheel the disk, two annular fric# opposite `sides of the disk outside said brackets, twoian'n'ular friction '.,brakes on ,opposite sides of the .disk inside said brackets, means to simultaneously move the outside plates toward each otherv against independent means to simul- "taneoeusly move the 'inside plates toward each yother againstA the disk.

' 5." A` disk brake comprisingl a friction disk.-

tnrning with the wheel, two` pairs of annular disk, a fixed plate and a# said plates arranged on op-A lto the wheels to the respective plates, a' fturnable ring, a series of wedgescarried on thereof, pairs of tplates, the two shdes of each pair 'connected and entering a pocket,

other 'in each pocket between the plug and one 4of fric-tion plates located atdiflerent distances from the wheelsaxis, the two plates of each pair loeat'eduon opposite sides ofthe disk, a series of pairs of slides secured to the respective plates ofeach pair, two turnable rings, a series of wedges carried on oneface of one ring and movable between thefslides of the respective pairs of slides of one series, a series of wedges -carried on one face of the other ring and movable'between the slides of the respective pairsof the other series, and' independentlyoperabley arms for operating the respective rings.
